Furthermore, a connecting plate is welded at the top of one side of the U-shaped frame, and the bottom of the connecting plate is connected with an ink absorbing sponge in a gluing mode.

Furthermore, fixed threaded holes are formed in two sides of the top surface of the fixing plate, and a plurality of fixed threaded holes are specifically formed in the fixing plate.

Further, the outer surface of the printing roller is cold-plated with a corrosion-resistant zinc layer.

Further, the outer surface of the printing roller is in contact with the bottom of the ink absorbing sponge.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. through setting up the leveling plate, the leveling plate is located printing roller the place ahead, and the leveling plate height is highly unanimous with the printing roller, and when the printing, the printing paper can be through the leveling plate, and then the leveling plate can make the printing paper be in the tiling state, and the printing roller printing of being convenient for reduces the printing defective rate.

2. Through setting up the blotting sponge, when the printing, the printing roller can rotate, finishes the back when the printing of a printing roller, can rotate to blotting sponge department, and at this moment, the blotting sponge can adsorb unnecessary ink on the printing roller, prevents that it from taking place the phenomenon of drippage, influences the printing effect.

3. Through setting up the air spring, the air spring can reduce the reaction force to printing roller itself production when printing roller contact printing paper, and then improves the printing quality to can prolong the life of printing roller.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a cylinder based on printing machine, includes fixed plate 1 and printing roller 8, bolt installation air spring 2 is passed through to fixed plate 1 bottom both sides, and 2 bottoms of air spring pass through screw installation U type frame 4, rotatory axle sleeve 9 of fixing bolt installation is passed through to both sides bottom in the U type frame 4, and is equipped with printing roller 8 in the U type frame 4, printing roller 8 both sides welding rotation axis 5, and rotation axis 5 rotate and connect rotatory axle sleeve 9, U type frame 4 both sides bottom welded fastening piece 10, and screw installation levelling plate 11 is passed through to fixed block 10 one side bottom.

Wherein, the top of one side of U type frame 4 welding connecting plate 7, and connecting plate 7 bottom veneer connection blotting sponge 6.

In this embodiment, as shown in fig. 1 and 2, during printing, the printing roller 8 rotates, and after one position of the printing roller 8 is printed, the printing roller rotates to the ink absorption sponge 6, and at this time, the ink absorption sponge 6 can absorb the redundant ink on the printing roller 8, so as to prevent the ink from dripping and affecting the printing effect.

Fixing threaded holes 3 are formed in two sides of the top surface of the fixing plate 1, and a plurality of fixing threaded holes 3 are specifically formed.

In this embodiment, as shown in fig. 1, a person can install the device into a designated printer using screws corresponding to the fixing screw holes 3.
